In pre-multiplied mode, the input graphic data is multiplied by the pixel blending factor (alpha_gp) and truncated to
the size of source format bits. For example, although the result of the multiplication of 8-bit data by 8-bit pixel
blending factor is 16 bits which is the first term of the blending equation in the
Table 9-2. N
ormal mode, the
supplied data is truncated to 8 bits that results the loss of the lower significant 8bits during calculation. In direct
32bpp modes, this loss data cannot be distinguished visually (+/- 1difference). But in direct 16bpp modes, the loss
data can make visually different result from the original. For example, in 4633 direct mode, the pre-multiplied Cb
data is truncated to 3 bits that result in the difference value from +15 to -15. This difference range can result to
visual difference. You cannot reduce the error that is resulted from the 3 bits input source. Thus, it is
recommended to use the 32bpp mode to use the pre-multiplied mode.
